Complete atrioventricular canal defects (CAVC) are a common heart defect, but few epidemiologic studies have evaluated nonsyndromic CAVC. Risk factors for nonsyndromic CAVC have not been well established.

Methods

To assess the relationship between risk for nonsyndromic CAVC in offspring and several sociodemographic and reproductive parental factors, including maternal diabetes and obesity, we conducted Poisson regression analyses, using data ascertained through the Texas Birth Defects Registry, a large, population-based birth defects registry. Data were evaluated for 563 nonsyndromic cases with CAVC.

Little is known epidemiologically about laterality defects. Using data from the National Birth Defects Prevention Study (NBDPS), a large multi-site case-control study of birth defects, we analyzed prevalence and selected characteristics in children b...

Although the descriptive epidemiology of atrioventricular septal defects (AVSDs), a group of serious congenital heart defects (CHDs), has been recently reported, non-genetic risk factors have not been consistently identified. Using data (1997-2005) f...

Background : Little is known about the etiology of nonsyndromic microtia. This study investigated the hypothesis that microtia is caused by vascular disruption. : Methods : The study analyzed data from the population-based National Birth Defects Prev...

IMPORTANCE : Critical congenital heart disease (CCHD) was added to the Recommended Uniform Screening Panel for Newborns in the United States in 2011. Many states have recently adopted or are considering requirements for universal CCHD screening throu...
